usb: dfu: f_dfu: Provide infrastructure to adjust DFU's Poll Timeout value

2013-12-18T18:53:19+00:00

It is necessary to deter the host from sending subsequent DFU_GETSTATUS
request in the case of e.g. writing the buffer to medium.

Here the timeout is increased when we fill up the whole buffer. This delay
allows eMMC memory to perform its internal operations.
Otherwise we end up with HOST's error regarding GET_STATUS receive timeout.

dfu: Export allocated dfu buffer size

2013-12-18T18:53:19+00:00

The method for exporting size of allocated buffer is provided.
It is afterwards used by USB's dfu function code.

dfu:core: Export dfu_{get|free}_buf functions

2013-10-20T21:42:40+00:00

Define the dfu_get_buf() and dfu_free_buf() as global functions.
They are necessary for zero copy buffer management, when DFU backend is
used for storing data.

dfu:core: Find DFU alt setting number by passing its name

2013-10-20T21:42:40+00:00

New function - dfu_get_alt() - has been added to dfu core. If present, it
returns alt setting's number corresponding to passed name.

usb:g_dnl:dfu: Download gadget and DFU function code clean up

2013-09-24T15:51:36+00:00

The download gadget code and DFU function lacks of proper declarations
for the case when a target board wants to use only one of available usb
functions.

Moreover the relevant declarations have been moved to consistent
localization (like ).

dfu: ram support

2013-09-24T15:51:35+00:00

DFU spec mentions it as a method to upgrade firmware (software stored
in writable non-volatile memory). It also says other potential uses of
DFU is beyond scope of the spec.

Here such a beyond the scope use is being attempted - directly pumping
binary images from host via USB to RAM. This facility is a developer
centric one in that it gives advantage over upgrading non-volatile
memory for testing new images every time during development and/or
testing.

Directly putting image onto RAM would speed up upgrade process. This and
convenience was the initial thoughts that led to doing this, speed
improvement over MMC was only 1 second though - 6 sec on RAM as opposed
to 7 sec on MMC in beagle bone, perhaps enabling cache and/or optimizing
DFU framework to avoid multiple copy for ram (if worth) may help, and
on other platforms and other boot media like NAND maybe improvement
would be higher.

And for a platform that doesn't yet have proper DFU suppport for
non-volatile media's, DFU to RAM can be used.

Another minor advantage would be to increase life of mmc/nand as it
would be less used during development/testing.

usage:  ram  
eg. kernel ram 0x81000000 0x1000000

Downloading images to RAM using DFU is not something new, this is
acheived in openmoko also.

DFU on RAM can be used for extracting RAM contents to host using dfu
upload. Perhaps this can be extended to io for squeezing out register
dump through usb, if it is worth.

dfu: unify mmc/nand read/write ops enum

2013-09-24T15:51:35+00:00

MMC and NAND independently defines same enumerators for read/write.
Unify them by defining enum in dfu header. RAM support that is being
added newly also can make use of it.

dfu: Extract common DFU code to handle "dfu_alt_info" environment variable

2013-09-24T15:51:35+00:00

New dfu_init_env_entities() function has been extracted from cmd_dfu.c and
stored at dfu core.

This is a dfu centric code, so it shall be processed in the core.

dfu: Make maximum DFU file size equal to default DFU data buffer

2013-09-24T15:51:35+00:00

Up till now the DFU maximum file size (to be written to e.g. eMMC)
was different from the DFU data buffer size. It caused errors when
one buffer was smaller than data to be written.

Now, the maximum DFU file size is equal to default DFU buffer size.
In spite of this, user is still able to manually adjust those default
values.

dfu, nand, ubi: add partubi alt settings for updating ubi partition

2013-08-26T19:56:34+00:00

updating an ubi partition needs a completely erased mtd partition,
see:
http://lists.infradead.org/pipermail/linux-mtd/2011-May/035416.html

So, add partubi alt setting for the dfu_alt_info environment
variable to mark this partition as an ubi partition. In case we
update an ubi partition, we erase after flashing the image into the
partition, the remaining sektors.
